override using echo

[kamranhameed]

folks. i am writing a simple shell script that prints the number from 100 to 200.

But my requriment is that when is should run it, it should not show me the output like

100 101 102 ... 200

intead i want that it shoud print 100, then override 100 and print 101 then override it and print 103 ... till 200.

How can we do that using echo


i am doing

echo -e -n "$var \r"

But its giving me nothing in output??

Any Ideas?

1) did you change permissions to +x ??

2) are you running it by
sh script
where script is the name of your script?

3) you should put a plain echo after the loop so to move to the next line otherwise the prompt will overwrite the output

4) This will happen very fast chances are you will only see the last number. Are you putting a delay into the loop so you can see the count progress??
